A painting thought to be the work of a famed Renaissance artist has been uncovered beneath centuries of dirt on the wall of a cathedral in Vienna, Austria. Found in St Stephen's Cathedral, the large wall painting was discovered on a wall that now sits above the cathedral's gift shop. Experts said the painting, which depicts Saints Catherine and Margaret, is the work of German artist Albrecht Dürer. Dürer worked as a theorist of the German Renaissance and also produced many prints.
